To all whom it may concern: backward a sufficient distance to give the Be it known that I, THEODORE .I. AMBERG, holding-rod b a proper projection.

The upper end of the wire is bent oval form of the perforation being for the purpose of giving greater freedom when the front edges of the sheets are raised. This freedom,

however, can be obtained by the use of round holes made larger than the rod or wire. It will also be understood that the means for attaching the sheets may be made of metal, cloth, or paper eyes attached to the back of each sheet, and when so made the rod 1) need not project within the body of the box, or it will not need to project out within the body as far as here shown.

WVith many of the holders it is difficult to pack the index-sheets for shipment or storage without having the holder injure the sheets or the holder itself become deranged. In the form shown in Fig. 4 it will be seen that by turning the sheets onto either one of the rearwardly-proj ecting parts of the holder and turning the holder, as shown in said Fig. 4, the sheets may be closely packed for shipment or for other purposes, so that no harm or damage can come to either the holder or the index-sheets, and thc projecting parts may be so closely fitted as to form a lock for holding them together in this position, if desired.

I do not limit myself to the particular form of the retaining-bends here shown, as they may be greatly varied at such bendings and still retain the double-holdin g and the threading or sheet-connecting features.

That which I claim as my invention, and desire to secure by Letters Patent, is-

An index-holder consisting of a stem of wire bent rearwardly at its upper and lower ends, provided at one end with holding projections extending in opposite directions from the stem and in a plane in rear thereof, and at its other end provided with an extension projecting laterally to one side of the stem, then curved in the direction of the length of the stem, and finally carried across to the opposite side of said stem.
